Journal ArticleDOI
Effect of the AlPO4 join on the pump-to-signal conversion efficiency in heavily Er-doped fibers
Mikhail E. Likhachev,Mikhail M. Bubnov,Kirill V. Zotov,Denis S. Lipatov,Mikhail V. Yashkov,Aleksei N Gur'yanov +5 more
TL;DR: The PAS host glass is advantageous in the case of large-mode-area active fibers and the presence of the AlPO(4) join results in the enhancement of the pump-to-signal conversion efficiency in the PAS EDFs.
Journal ArticleDOI
Sub-MW peak power diffraction-limited chirped-pulse monolithic Yb-doped tapered fiber amplifier
Konstantin K. Bobkov,Alexey V. Andrianov,M. Y. Koptev,S. V. Muravyev,Andrei E. Levchenko,V. V. Velmiskin,Svetlana S. Aleshkina,Sergey L. Semjonov,Denis S. Lipatov,A N Gur'yanov,Arkady Kim,Mikhail E. Likhachev +11 more
TL;DR: A novel amplification regime in a counter-pumped, relatively long (2 meters), large mode area, highly Yb-doped and polarization-maintaining tapered fiber, which offers a high peak power directly from the amplifier.
Journal ArticleDOI
Millijoule pulse energy 100-nanosecond Er-doped fiber laser.
Leonid V. Kotov,Mikhail E. Likhachev,Mikhail M. Bubnov,Oleg I. Medvedkov,Denis S. Lipatov,Aleksei N Gur'yanov,Kirill I. Zaytsev,Mathieu Jossent,Sébastien Février +8 more
TL;DR: This work reports, for the first time, on a single-mode millijoule-level 100-nanosecond Er-doped fiber laser operating near 1550 nm that produces pulses with energy as high as 1 mJ at repetition rates of 1-10 kHz.
Journal ArticleDOI
Fabrication and optical properties of fibers with an Al2O3-P2O5-SiO2 glass core
Mikhail M. Bubnov,V. N. Vechkanov,A N Gur'yanov,K.V. Zotov,Denis S. Lipatov,Mikhail E. Likhachev,Mikhail V. Yashkov +6 more
TL;DR: In this article, a process has been developed for the fabrication of preforms and fibers with Al2O3-P2O5-SiO2 glass cores, and their optical properties have been investigated.
Journal ArticleDOI
Spatial beam self-cleaning and supercontinuum generation with Yb-doped multimode graded-index fiber taper based on accelerating self-imaging and dissipative landscape
Alioune Niang,Tigran Mansuryan,Katarzyna Krupa,Alessandro Tonello,Marc Fabert,Philippe Leproux,Daniele Modotto,Olga N. Egorova,A. E. Levchenko,Denis S. Lipatov,Sergey L. Semjonov,Guy Millot,Vincent Couderc,Stefan Wabnitz +13 more
TL;DR: In this article, the authors demonstrate spatial beam self-cleaning and supercontinuum generation in a tapered Ytterbium-doped multimode optical fiber with parabolic core refractive index profile.
